The unique selling points of the OPTS

The OPTS can lift up to six people simultaneously and goods up to 2,000 kg. This combination discerns the OPTS from all other systems currently available in the market.

After a one day and on-site training, the OPTS unit can be operated by client’s staff.

The OPTS unit moves up to six people per operation and completes the operation quicker, also in horizontal movements. The movement is 10 to 12 times quicker and more efficient in horizontal movements. In vertical movement, the savings in time increase by even a higher factor.

The OPTS hooks on the load and transports it to the desired location in the same simple movement (fully motion compensated).

The structure can be approached horizontally with cargo, allowing for transporting cargo between decks. Current systems can hoist up only, approaching the structure from above. This is why it is often difficult or impossible to transfer goods to certain structures.

In the event of emergencies, the OPTS unit has no fixed coupling or connection into the offshore structure. This gives the option of several people getting on or off and transporting them back to the ship quickly. The OPTS unit can then go back to the basic position on deck, irrespective of conditions.

The OPTS unit works from the deck, like the employees; they can safely go from the base to the workplace without having to bridge a height difference. Foundation is required, approval by notified body is required to check deck strength of intended vessel.

The OPTS unit offers the option of being lowered over the deck railing. This enables the ship to pick up people from sea, for example safety and rescue, or off boarding and on boarding divers, inspecting and maintaining the hull etc. It allows for performing a large variety of operational possibilities.

The OPTS unit is located on deck with a footprint of 8 by 8 feet. Its relatively light weight (well under 15 tonnes) hardly affects ship stability, enabling its application on very small work vessels.

The OPTS can be remote-controlled. Each movement made is logged. Subsequently, the movement can be repeated virtually fully automated, whether or not linked up to the vessel’s DP system.

The 40-foot transportation frame of the OPTS makes it suitable for quick and cheap regular transport. This allows for quick mobilisation and demobilisation of the system. The ongoing development will allow the OPTS also be moved from ship to ship at sea or during operations.
